Abstract

L'invention concerne un dispositif à percussion de type nouveau. Un moteur 1 entraîne une pompe 2 alimentée par un réservoir pressurisé 3, ainsi qu'un distributeur rotatif 5 pour faire circuler un fluide hydraulique successivement dans les sens 12 et 13. La chambre annulaire délimitée par un piston 10 d'un marteau 8 est ainsi successivement connectée, à une fréquence élevée, à une source à haute pression et au réservoir 3. La chambre principale située à l'opposé de la chambre annulaire est repoussée par un coussin gazeux 16 délimité dans un manchon tubulaire 11. Application : dispositif d'une grande souplesse d'utilisation
